47.12 meters cubed
The formula for the volume of a cone is:
V = 1/3 * pi * r^2 * h
Substituting the values given (where the radius, which is one half of the diameter, is equal to 3), gives you:
V = 1/3 * pi * 3^2 * 5
V = 1/3 * pi * 9 * 5
V = 1/3 * pi * 45
V = 15 * pi
V = 47.12 meters cubed
Volume = pi525 = 393 cubic meters rounded to the nearest integer
diameter = 220/pi meters

-- Exact circumference = 2pi meters -- Approximate circumference = 6.283 meters
The Sun's diameter is approximately 1,391,000,000 meters in length, which is over 100 times the approximate diameter of the Earth (12,756,200 meters).
